Molar conductances of NaCl and KCl in 0~100%(ω/ω) CH3OH-H2O have been measured by using the alternating conductance bridge method resembling that of Shedlovsky. The results show that the lidriting molar conductances (Λ0) of both NaCl and KCl have the lowest curve points around 55%(ω/ω) CH3OH and the limiting molar conductances (Λ0) of KCl are larger than that of NaCl in 0~100%(ω/ω) CH3OH-H2O mixtures, which can be accounted for in terms of the micro-structure and ionic solvated situation of NaCl and KCl aqueous methanol solutions. Furthermore, the experimental limiting molar conductances (Λ0) for KCl-CH3OH-H2O system in this work are critically compared with that of Ands, which shows that the measured results in this work are more reliable.
